From 185af4d6668e4805d18d1bdf21dfec89d680fee3 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Fri, 24 Oct 2014 17:20:27 -0700 Subject: Input: psmouse - remove unneeded check in psmouse_reconnect() psmouse_reconnect() will not be called if psmouse driver is not bound to the serio port, so there is no point in checking that. Also, as coded, it introduces potential NULL dereference in psmouse_dbg() in case psmouse is indeed NULL. Let's just remove it.
